At the end of each season, The Elias Sports Bureau ranks all MLB players numerically based on a bunch of stats. Every player is categorized in one of five position groups and by league. The rankings cover a two-year time period. They are used to determine whether free agents are Type A, Type B, or neither. If you'd like a reminder on how draft pick compensation works, read up here.
Eddie Bajek of Detroit Tigers Thoughts reverse-engineered the Elias Rankings last year. Eddie's incredible work was made possible in large part due to information provided by ESPN's Keith Law. Eddie is now providing the rankings exclusively to MLB Trade Rumors. These projections cover the 2008-09 seasons. Note to journalists: if you use these projections in an article, please credit Eddie Bajek and MLB Trade Rumors.
